Letters Patent No. 91,070, dated J ans 8, 1869.

IMPROVED POLISHING AND CLEANSING-POWDER.

The Schedule referred to in these Letters Patent and. making part of the same.

To all whom it may concern:

Be it known that I, J. W. BATES, of St. Paul, in

the county of Ramsey, and State of Minnesota, have invented certain new and useful Improvements in Powder for Cleaning Teeth and Metals; and do hereby declare that the following is a full,clear, and exact description thereof.

The nature of my invention consists in themanufeature of a powder from peat, which may be used for the purpose of cleaning teeth, ivory, silver, glass, or anything that needs a fine polish.

In order to enable others skilled in the art to which my invention appertains, to make and use the same, I will now proceed to describe the process by which this powder is obtained.

After the peat has been taken out of the bed, it is burned under cover, and the ashes obtained bolted through a fine bolt. The bolted ashes are then mixed with cold spring-water, and the mixture strained, or filtered. I then let it stand snfiicient time to let the 'grit settle at th'eb ottoniflvhenfi pour it from one vessel to another, using only the top each time, until it is thoroughly cleansed from all impurities. It is then poured into pans, and dried over a slow fire. After drying, it comes out of the pans in the shape of cakes,

which cakes are put through a mill, and pulverized to a fine powder.

'lhis powder is eminently adapted tocleaning any article requiring a fine .polish. As a tooth-powder, it

is unsurpassed, possessing all the chemical properties which tend to preserve the enamel of the teeth, as it is purely vegetable, containing no acids of any kind. WVh'en put up for tooth-powder, it may be flavored in any manner desired.

Having thusfnlly described my invention,

What I claim as new, and desire to secure ,by Letters Patent, is

1. The above-described process forobtaining a cleaning-powder from peat, substantially as herein set forth.

2. Preparing peat in such a manner as to produce a powder suitable for cleaning teeth, or any article needing a fine polish, substantially as herein set forth.

3. A cleaning-powder, made from peat, substantially as herein set forth. p

In testimony that I claim the foregoing, I have hereunto set my hand,.this 15th day of March, 1869.
